A compound contains three elements `A,B` and `C`, if the oxidation number of `A=+2B=+5` and `C=-2` then possible formula of the compound is

A

`A_2(BC_3)_2`

B

`A_3(BC_4)_2`

C

`A_3(B_4C)_2`

D

`ABC_2`

Text Solution

Verified by Experts

The correct Answer is:
B
In `A_3(BC_4)_2`
3 x oxidation number of A + 2 [oxidation number of B + 4 x oxidation number of C]=0
3 x (+2) + 2 [ 5 + 4 x (-2)]=0
6+2 [-3]=0
